MARKING MACHINE.

Application filed October 9, 1922. Serial No. 593,416.

This invention relates to marking machines of the type comprising aplaten or work support and a printing head movable toward and fromtheplaten to make the printed: impression. Each printing head is providedwith a lurality of independently adjustable type w eels.

One feature of our invention relates to a novel manner of locking;' theadjustable type.

wheels in place and wheels individually.

In the drawings, Fig. 1 is a side view of a or setting the type markingmachineembodying our invention.

Fig. 2 is a partial front view thereof.

Fig. 3 is a transverse section through the printing head.

Fig. 4 is a section through the printing" wardand from a platen or work,support 5,

on which the work is supported.

The rinting head herein shown is constructef with a lurality ofindividually adjustable type w eels 6, said type wheels being rotativelymounted on a hollow sleeve or support 7 carried in the printing head.

Each type wheel is provided with a plural ity of type characters, as isusual in machines 1 of this class. The printing head maybe given itsvertical movement by any suitable mechanism.

The type wheels are formed with notches 8, between the type characters,as is usual in machines of this character, and said wheels are lockedfrom turning movement by'a looking bar 29, which fits the alignednotches of the type wheels. This locking bari's formed with a notch 10.of the width of the type wheels 6, and said locking bar is slidablymounted in guides 11, so that the notch '10 can-be brought into registerwith any one of the t pe wheels 6. The particular type wheel w 10b is inregister with the notch is free to be turned while the others are lockedfrom turning movement as will be obvious.

For adjusting the type wheel which'is. thus unlocked, we have provided asetting dog12, which is carried by a" slide 13, and

operates in agroove 14, formed in the supporting sleeve 7. This slide"13 is connected toa collar 15' which is fast on a member 16 L thattelescopes into the supporting sleeve .7.

tion between the locking bar 9 and the collar .15, however, is one whichpermits the collar and its supporting member 16 to turn about theiraxes. This connection comprises a ring 17 which is swivelled on thecollar 15, and to which the end of the locking bar 9 is secured by meansof a clamping screw 18.

In setting any type wheel, the collar and member 16 are movedlongitudinally of the sleeve 7 tobring the notch 10 opposite the typewheel which is to be set, thus unlocking said type wheel.

Each type wh with a plurality of notches 19, one for each typecharacter, and when the type wheels are locked in operative position,thenotches of the various type wheels are in alignment with each other.These notches are constructed to receive the dog 12 and the con- 1 isprovided on its interior struction is such that when the collar 15 is Vtype wheel capable of supporting type char acters, each of whichrepresents a complete word. This is especially desirable in themanufacturing of shoes, where it is desired to stamp shoes or partsthereof, or the cartons therefore, with the size number, case number,and some word describing the character of the shoes. 7

We have herein shown the printing head as including one type wheel 22,which is much wider than the other type wheels and.

which is thus adapted to have on its periphery type characters each ofwhich are constructed to form printed words.

"In order to provide for unlocking this wide type wheel to permit it tobe set,.wev have provided the locking bar 9 with a mov-' able section23, which has a width equal to that of the wide type wheel, and whichwhen v removed, produces a notch or openin the bar as wide as said widetype whee so that when the locking bar is adjusted to bring this widenotch opposite the'wide type wheel then the latter will be unlocked.

This movable section 23, is shown as pivoted to the locking bar 9 at 24and when it is swung into line with the bar, it forms part of thelocking portion thereof, but when it is swung into its open position,shown in Fig. 4, it provides the wide notch that permits the unlockingof the wide type wheel 22.

The type characters are inked by means. of an inking roll-25, hereinshown. as carried by two swinging arms 26, which are pivotally connectedat their upper ends, as shown at 27, to uprights 23, extending; from theprinting head. The swinging arm 26 carries the ink roll across the;surface of the type characters when the printing head is elevated, andwhen said printing head is depressed into. printing position said armsswing into dotted line position Fig. 1, therebycarryingthe-printing rollagainst an inkdistributing roll 29. This ink-distributing roll isrotatably mounted in a bracket 30, secured to the frame 1. Said bracketalso supports theink reservoir 31, in which operates anink supply: roll32.

33 indicates a transfer roll which is ournalled in a rocking memberpivoted to the bracket: at 35, rocking movement of said member carryingthe transfer roll from the ink-distributing roll 29. to. the supply roll32. The rocking member 34 is acted on by a spring 36 which is secured atone end to the bracket 30 and at the other end to a pin 71 extendingfrom the rocking member, the spring tending to hold the transfer roll 33in contact with the ink-distributing roll 29.

37 indicates a dog pivoted to the rocking member 34 and having a notch391 The swinging arm 26 carries a projection 33 at its lower end whichco-operates with the dog 37 to swing the rocking member. hen the dog isin the full line position Fig. 1 then the notch 39 is in the position toreceive the projection 33 as the arms'26 swing backwardly and when thisconditionobtains the rocking member remains stationary but if the dog isturned to carry the notch 39 out of the path of movement oftheprojection 38 then when the arm 26 swings backwardly said projectionwill engage 'the dog and turn the rocking member to swing the transferroll into contact with the ink-distributing roll. The transfer rollwillthen take up ink and when the armsv operates, said locking pawlbeing slidably mounted in the bracket guide 49 and being acted on bysprings 56. This. locking pawl when in operative position preventsupward movement of the platen, although the latter is at all times freeto move downwardly. The locking pawl is withdrawn. at proper times by anarm 58 fast on a rock shaft 57, the latter having an arm 60 rigidtherewith to which isv connected a link 61 which is urged upwardly-by aspring 62'and is depressed atthe time that the printed impression is:made by means ofa'cam 63 which is mounted on a shaft 64. operating intimed relation with the movement of the head 4. link 61 and the latterhas a slot 66 through which the shaft (54 extends. This construction oflocking and unlocking the platen. is.

not, however, herein claimed. lVhile we have illustrated herein aselected embodiment of our invention we do not wish to be limited to theconstructional features shown. We claim:

1 In a marking machine, the combination;

with a hollow supportingsleeve, of a plurality of type wheels rotatively.mounted thereon, one of which type wheelsis. wider than the other, alocking bar engaging the type Wheels and locking them from rotation,said'bar having a notch of a width corresponding to the width of thenarrower type.

2. Ina marking machine, the combination:

with a hollow supporting" sleeve having a.

longitudinal groove, of a plurality'of type wheels rotatably mountedthereon, each type wheel having a notch, a type-setting dog slidablymounted in said groove and adapted to beshifted into engagement with anotch in any one of the type wheels, said sleeve being rotatably'mounted therebynto adjust theparticular type wheel witlr which the doghas engagement andfia locking bar situated exterior to the type wheelsand lock-. ing them from 'movement, said bar being This cam engagesaroll 65 on the.

adjustable longitudinally to release individual type wheels.

3. In a marking machine, the combination with a hollow supporting sleeveadapted to rotate about its axis, said sleeve having a longitudinalgroove, of a plurality of type wheels rotatably mounted on said sleeve,each type wheel having a plurality of notches, a setting dog slidablymounted in said groove and adapted to be brought into engagement with anotch of any type wheel,

a member movable axially of said sleeve and to which the setting dog isconnected, and a locking bar secured to said member and operating tolock all the type wheels except 15 the one with which the setting doghas engagement.
